Application filed April 7,

This invention relates to a mangle or ironing machine particularly of that type which is electrically operated and power driven. The object of the invention is tov generally improve and simplify the construction and opera-tion of machines of the character described; to provide a machine in which the shoe or iron may b e moved or foi-ced into engagement with a padded roller by means of a foot actuated mechanism, thereby leaving thehands of the operator free to handle the articles to be'ironed; to provide a mechanism whereby pressure is Aapplied to the center .of the shoe or iron when being depressed s0 as to exert uniform pressure from end to en d; to provide spring actuated means whereby the iron is normally held in raised or inoperative position with relation to the padded roller; to provide'a structure whereby the padded roller is supported, journaled and driven from one end and in conjunction therewith, to provide a cross head structure and guide whereby the iron may also be supported at one end.

One form which the ironing machine may assume is exemplified in the accompanying drawings, in which: f

` Figure 1 is a perspective view ofthe ironing machine partly broken away and also `partly shown in section.

Figure 2 is a cross section on line II-II. Referring t'o the drawings in detail and particularly Figure 1,V A indicates the padded roller of the machine and 2 the iron which cooperates therewith. The roller and the iron are both supported at one end and the iron is movable vertically into and out of contact with the padded roller as will hereinafter be described. A roller and iron sup-4 ported in this manner is particularly convenient and efficient, as it leaves one end of the roller and the iron unobstructed so that clothing may be inserted from one end if desired, for instance, when ironing lace edgas.; ing on articles such as wearing apparel and the like. A common support is provided both for the roller and the iron and this is generally indicated at B. The support consists of a late 3 to which is secured a housing 4. T is housing contains an inner jourH nal not shown and an exterior journal 5. These journals form a support for the shaft of the roller A and the housing also forms a cover for a worm gear 6 secured on the 192s. semina. 100,250.

shaft. The lower part of the housing is eX- tended as at 7 and this lextended portion forms a bearing for a driving shaft 8 and it also forms an enclosure or housing for a worm pinion 9 which constantly meshes with the worm gear 6 and drives the same. The pinion 9 is secured on the shaft 8 and as such rotates in unison with the same when the shaft is driven. The shaftr 8 may be driven from any convenient source such as an electric motor or the like, not illustrated. The plate 3 doesnot only form a support for the housing 4, but it also forms a guide for a cross head member generally indicated at C. The cross heady member Cdis formed integral with one end of the iron 2 or it may` be secured thereto. It consists .of a plate 10 on which is formed side flanges 11. These flanges engage the outer edges of the plate 3 and they form supports for auxiliary guide plates 12 which are 'secured to the ianges 11 by means of screws 13. The flanges 11 are a so provided with extending lugs 14 which form supports and guides for a yoke member` consisting of two vertical rods F15 and spring arm sections 16: The rods 15 vare freely movable in the lugs v14 and they are extended downwardly through a' foot plate 17 formed on the lower end of the plate 3. Springs 18 are interposed between the foot plate -17 and the lower ends of the lugs 14 and their function will hereinafter be described. The spring arms 16 of the yoke are connected by a cross section 19 which engages thecenter top portion of the iron and the lower ends of the rods l5 are connected by a cross bar 20, to which is attached aV chain 21, the opposite end of the chain being connected to a foot treadle 22.

The machine as a whole may be supported on the edge of a table by means of the foot flange 17 on the plate 3 and by screws, bolts 0r other suitable means to rigidly secure the machine to the table. In the present instance, the machine is shown as supported vby a standard 23. This standard is provided with a collar 24 on its upper end which extends into the lower portion 7 of thehousing 4 and it is there secured by means of a \set screw 25. Any suitable method of'supporting the machine may however be employed. In actual operation, itwill be noted that the iron 2 vis electrically heated and when it is desired to operate the machine, it

v iron. The iron and the cross head will thus is Vonly hecessaryto turn -on the switch 26 and to start the motor or other driving unit, Roller A -will under these conditions rotate at a uniform speed and articles to be ironed are inserted4 between the roller and the lower face of the iron which is maintained at the proper telnperature by means ofthe heating units lmounted within the iron. It is of course f/necessary to apply pressure when the clothing 41s assmg under the iron and this is accomp ishedl in the present instance by merelydepressing or stepping on the treadle 22. Pressure on this pedal exertsl a pull on the chain 21 and the cross bar 20. This in turn pulls therods 15 of the yoke dbwn Wardly and as such transmits a downward movement `to the cross head C and the iron proper, this being due to the fact that the rods 15 terminate in spring arms 16 and to the crossbar 19 which applies a yielding pressure `to the top. center portion of the move downwardly on the guide plate 13 and as such will compress the springs 18, any' pressure desired being applied by stepping on or applying more orless pressure on the treadle 22. When the article is passed through, the operator merely releases pressure on the treadle and the iron is instantly elevated, as thetension of the springs 18 which have been placed under "compression during. downward movement of the iron,

will automaticallyv raise it to elevated or normally inoperative position.

From the foregoing, it is obvious thatA v one end of the roller and the iron is free and unobstructed, thus permitting the ex'- v treme end of the roller and the iron to be stalled in a laundry, a kitchen, or at almost any point convenient.

While certain features .of the present in- Yvention are more orless specifically illustrated, We Wish it understood that varying changes may be resorted to within the scope of the a p'ended claims and similarly, that ,l the mate ials and finish of the several parts employed may be such as varyingy conditions orf the dictates ofl the manufacturer may Y demand.

Having thus described our invention, What' we clalm 1s:

1. In an ironing machine, a stationary gulde member, a shaft journaled and supported at one end 1n said guide member, a

roller secured on the shaft, an iron disposed.

above the roller and extending substantially from end to end thereof, a depending cross head vertically movable on the guide vertically movable on the guide member and secured to .one end of the iron and forming a support therefor, spring actuated means whereby the iron is normally held in an clyevated position withl relation to the roller, and means engaging the iron at a point substantially centrally relative to its length, whereby uniform pressure isexerted from end to end of the iron upon forcing the same downwardly into engagement with the roller.

3. In an ironing machine, a stationary guide member, a shaft journaled and supported at one end in said guide member, a roller secured on the shaft, an iron disposed above .the roller and extending substantially ,from end to end thereof, a cross head vertically movable on the guide member and secured to one end of the iron and forming avsup ort therefor, springfactuated means where y the iron is normally held in an elevated position with relation to the roller, a treadle mechanism from which movement is transmitted to force the iron downwardly into engagement with the roller means foxl rotating the roller said Ameans including` power transmitting devices carriedbysaid stationary guide member. i

4. In an 'ironing machine, a stationary guide plate, a shaft journaled and supported atl one end in said guide plate, a roller on said shaft, an iron disposed above said roller, a cross head on said iron having guidel ways therein to receive the guide plate whereby vertical movement f the iron on the guide plate is permitted, meansfor driving said roller, and other means for imparting vertical movement to the iron.
